0.65x+121-0.55x=108
Use the distributive property to multiply 0.55 by 220-x.
0.1x+121=108
Combine 0.65x and -0.55x to get 0.1x.
0.1x=108-121
Subtract 121 from both sides.
0.1x=-13
Subtract 121 from 108 to get -13.
x=\frac{-13}{0.1}
Divide both sides by 0.1.
x=-130
Expand \frac{-13}{0.1} by multiplying both numerator and the denominator by 10. Anything divided by one gives itself.
